CMAKE_FIND_USE_INSTALL_PREFIX

Added in version 3.24.

Controls the default behavior of the following commands for whether or not to search the locations in the CMAKE_INSTALL_PREFIX and CMAKE_STAGING_PREFIX variables.

• find_program()

• find_library()

• find_file()

• find_path()

• find_package()

This is useful in cross-compiling environments.

Due to backwards compatibility with CMAKE_FIND_NO_INSTALL_PREFIX, the behavior of the find command change based on if this variable exists.

CMAKE_FIND_USE_INSTALL_PREFIX	CMAKE_FIND_NO_INSTALL_PREFIX	Search
Not Defined	On	NO
Not Defined	Off || Not Defined	YES
Off	On	NO
Off	Off || Not Defined	NO
On	On	YES
On	Off || Not Defined	YES

By default this variable is not defined. Explicit options given to the above commands take precedence over this variable.

See also the CMAKE_FIND_USE_CMAKE_PATH, CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH, CMAKE_FIND_USE_SYSTEM_ENVIRONMENT_PATH, CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY, CMAKE_FIND_USE_PACKAGE_REGISTRY, and CMAKE_FIND_USE_PACKAGE_ROOT_PATH variables.
